CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 267,337, dated November14, 18862. Application filed June 30, 1882. (No model.)

' To all whom ti may concern:

Be it known that I, JOSEPH EISELE, a citizen of the United States ofAmerica, residing at Lafayette, county of Tippecanoe, and

' State of Indiana, have invented certain new and useful Improvements inOar-Axle Boxes and Lids therefor; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, in which- Figure 1 is a view in sideelevation of theimproved car-axle box with thelid in placethereon. Fig.2 is a longitudinal central section Fig. 3, a view in plan with the lidremoved,

:5 and Fig. 4 a sectional view on line 4 4 of Fig. 1.

In the trucks of railroad or like cars the boxes which inclosethejournalsofthe ear-wheel axle and carry the brasses or bearings forsaid journals and the necessary lubricant are usually provided with alid or flap on their outer side, whereby the interior of the box isreadily accessible and the condition ofthejournals, brasses, packing,and lubricant open to quick inspection at all times when the car is atrest.

My invention relates to car-axle boxes and lids therefor; and itconsists ofcertain improvements in construction and combination 0 ofparts, all as hereinafter set forth,and more particularly. defined inclaims.

Referring to the drawings, A represents the casin g or car-axle boxproper, formed preferably of cast metal, having the flanged seatato 3 5receive the arch-bars b of thecar-truok, as usual,

and constructed upon its interior in any wellknown manner-that is tosay, my invention is not dependent upon. any peculiarities of internalstructure, but is equally applicable to 4.0 the boxes of most diversepattern.

From the upper face of the box A, and somewhat in front of the flangedseat a, there is formed in each side wall of the box a groove, 0, ofnearlysemicircular cross-section, that runs 5 downwardly and outwardlyin said side wall, approximately on the are of a circle, until itintersects and merges into a lateral groove, d, of like contour orcross-section, the frontedge of which said groove disin arightline,slightly divergent or out of a parallel, with the front or 0 bearingface, 6, of the box Aas descent is made in said-groove d. The front orhearing face,

0, of the box A is slightly beveled or rounded at its outer corners tosnugly fit a corresponding fillet, g, formed along the inner corner of 5the box-lid B, now to be described.

The lid B consists of a flat plate that rests with its inner faceagainst the bounding-surfaces of the opening in the box A, and has uponits outer face the raised ribs or projec- 6o tions it to strengthen it,which ribs are contin uous with like ribsformedon the fiangesor arms 0,that depend at right angles from both sides of the plate B. The arms 0have upon their lower ends and at'the inner side a hemispheri- 6 callug, t, which snugly fits, in manner free to move, the grooves c d,formed, as described, in the side walls of box A. At theju'nction ofthedepending arms 0 with the body of the lid B the inner corner or edge,instead of being a right angle, is made with a rounded fillet, g, whichaffords greater strength to the casting, and has certain otherincidental advantages, presently to be detailed. Aset-screw, bolt, pin,or the like, 70, is inserted into a perforation, m, madein the upperface of the box A, near its front end. The box A being in position uponthe car-truck,With the journal of the ear-wheel axle, the brasses,&c.,in place therein, the lid B is applied to the box by arranging saidlid in position (shown by dotted lines, Fig. 1) so that the lugs i shallenter and follow the grooves c d, the lid as it drops in said groovesbeing turned to the front, so that its face shall bear against thesloping face of the box, the divergout edge ofgroove d causing the lidto be drawn more tightly to its seat the farther that arms 0 andattached lugst'descend in said grooves, so that at the end of its travelthe lid makes a practically dust-proofjoint with the box, andoffectually secures the j ournal and brasses from destructive cutting orthelubricant from waste. The pink is now inserted in the perforation m,whereupon the lid may not be removed, shaken off, or lost, for it willbe noted that when said lid is raised, as shown in Fig. 2, to allowaccess to the interior of the box, the pin 70 is of such height as tosustain the lid in part, so that the lugs i on the arms 0 of the lid areseated in the upper ends of the transverse grooves (I, and may not dropdown far enough to clear the sharp corner or junction j of the grooves 0(I, and so pass upward in said grooves 0; and yet it will be noted thatby simply taking out the pin 70 before the lid is lifted the lugsi willbe free to travel in both of the grooves c d and the lid be removedentirely from the box, if at any time desired, which facility ofoperation distinguishes my device from others of like characterforexample, Patent No. 192,199, Susemihl and Hewitt, June 19,1877, whereinthe truck must bejacked and the arch-bars 1) taken oif before the lidcan pass back and out of the lugs on the axlebox, by which it isretained.

Aside from the obvious advantages which my device possesses, in commonwith others of its class-that is, sliding or wedge lids-over the oldform of hinged lids having bolts, pins, or springs to hold them inplace, which various parts must be fitted, and which are apt to workloose, to become broken and lost. Said device possesses some advantagespeculiar to itself. Thus when the box A is molded the side grooves ofthe box, being cut in the pattern itself, form their own core or mold,so that they are always in the precise position desired, leaving no filmto be cut away, which results from a displaced core when the box is castwith projecting ears or lugs. The front vertical edges of the box beingrounded, instead of angular, take a sharper cast, so that they closelyfit into the fillets g of the lid and secure a dust-proofjoint withoutneed of extra labor in fitting.

The relation of the side grooves is such as to always retain the lidtightly in place, and yet to allow for its being quickly lifted orentirely removed at any time when the car is at rest without delay ofany kind. Broken lids or lids carelessly lost may be manifestly replacedupon discovery of defect, subjecting the 5 journal and brasses to nodestructive exposme, which must be necessarily incurred for want of ajack or the like when using the other forms of box. There being noprojecting ears or lugs to the box, it is less liable to damage, and thedelays in use of a car, made necessary in restoring a broken box,materially diminished. The guard-pin 7; is subject to no strain,

and is consequently always in position with respect to the lid, isneither lost itself, nor permits the loss of the lid from anyjolt orjerkof the car.

The shape and proportions of the several parts herein described asdistinctive of my device may be varied to adapt said parts to theseveral kinds of journal-boxes now in use upon railways withoutdeparting from my invention, which is not confined in strictness to theprecise details as set forth, but includes as well their substantialequivalents.

I am aware that it has been proposed to provide a car-axle box withgrooves; but,

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Acar-axle box havinginterseetinggrooves in its side walls to receivethe arms depending from the lid of said box, substantially as described.

2. The lid of a car-axle box, the depending arms of which are providedwith projecting lugs, substantially as set forth.

3. The combination, with a car-axle box having grooves in its sidewalls, of a sliding lid, the depending arms of which are provided withprojecting lugs to enter said grooves, substantially as described.

4. The combination,with a car-axleboxhaving intersecting grooves in itsside walls, of a sliding lid, the depending arms of which are providedwith projecting lugs to enter said grooves, substantially as described.

5. The combination, with a car-axle box having intersecting grooves inits side walls, of a guard-pin and a sliding lid, the depending arms ofwhich project into said grooves, substantially as set forth.

6. The combination, with a car-axle box having intersecting grooves inits side walls of substantially semicircular cross-section, of aremovable guard-pin and a sliding lid, the depending arms of which haveapproximatelyhemispherical projections to fit said grooves,substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of June,A. I). 1882.

JOSEPH EISE'LE.
